The catch
Ooni Koda 2
On the published figures, it is 5.27 lb heavier.
Side by side
Koda 2 is the choice when a 14-inch pizza is a genuine requirement, or when its selected peel-and-cover bundle fills gaps in your equipment. Pi Prime is the choice for 12-inch propane pizza in a 30-pound body. Each is an outdoor gas oven, and Ooni's recovery claims measured against Koda 12 do not show any recovery advantage over Pi Prime.
Before you buy
Using the square of the diameter ratio, a 14-inch round pizza has about 36.1% more nominal surface area than a 12-inch round pizza. Koda 2 is the one rated for that larger size. Pi Prime still suits a household that makes individual 12-inch pizzas, and a larger pizza does not guarantee a proportionally larger number of servings.
Where this comes from
The calculation is 14 squared divided by 12 squared, minus one. Dough thickness, toppings and appetite stay outside it, which means it makes no serving or throughput claim.
The catch
On the published figures, it is 5.27 lb heavier.
The catch
Its pizza rating stops at 12 inches.

The Koda 2 Essentials bundle and Pi Prime are compared on 14-inch versus 12-inch pizza, included tools and realistic carrying trade-offs.
This one comes down to rated pizza size and fuel first, then to the limits of your own setup.
Which one fits
Pi Prime is rated for 12 inches, and Koda 2 supports that diameter.
Pi Prime's published body weight is lower, though how well it suits carrying still varies by person.
Both are part of the selected Koda Essentials listing.
Pi Prime is not tested in Ooni's Koda 12 comparison.
In practice
Using the square of the diameter ratio, a 14-inch round pizza has about 36.1% more nominal surface area than a 12-inch round pizza. Koda 2 is the one rated for that larger size. Pi Prime still suits a household that makes individual 12-inch pizzas, and a larger pizza does not guarantee a proportionally larger number of servings.
The calculation is 14 squared divided by 12 squared, minus one. Dough thickness, toppings and appetite stay outside it, which means it makes no serving or throughput claim.
Koda 2 is 35.27 lb, and Pi Prime's stated 30-pound weight is 5.27 lb below that. If the oven is moved often after cooling, that can matter, but Koda's selected bundle includes a carry cover that may suit storage. Neither weight counts a propane cylinder, and neither proves that a particular person can carry it comfortably.
Published oven weights are what the subtraction compares. Look at handles, packed shape, route and table height separately, and follow the instructions for disconnecting fuel and cooling down.
Although the oven is rated for 14-inch pizza, the chosen Koda 2 Essentials bundle comes with a 12-inch peel. If you are buying so you can regularly make a full 14-inch pizza, confirm that you have a suitable launch tool and do not assume the bundle's peel matches the maximum diameter.
The exact bundle contents and the oven capacity are the basis for this conclusion. Pi Prime's package needs a separate peel check too, which means tool planning matters for both.

Ooni, 14-inch propane oven essentials bundle
Ooni's newer tapered flame and a thicker stone give this compact gas oven faster recovery between 14-inch pizzas.

Solo Stove, 12-inch propane oven, stainless steel
New cooks can find the useful heat zone fast on this simple propane oven, thanks to its wide mouth, two-piece stone and clearly marked heat dial.
Spec by spec
| Spec | Ooni Koda 2 | Solo Stove Pi Prime | In practice |
|---|---|---|---|
| Rated pizza size | Up to 14 inches | Up to 12 inches | Koda takes a larger diameter, provided the tool and recipe match. |
| Fuel | Propane | Propane only | An appropriate outdoor gas setup is needed for either. |
| Published body weight | 35.27 lb | 30 lb | By the published figures, Pi Prime weighs 5.27 lb less. |
| Selected accessories | 12-inch peel and Koda 2 carry cover in Essentials bundle | Oven package without a listed peel | Having the peel included with Koda does not make it a 14-inch peel. |
| Stone | 15 mm cordierite | Two-piece cordierite | The stones are built differently, and there is no measured recovery comparison. |
| Published high heat | Up to 950°F | Up to 900°F in current guidance | Maximum claims cannot tell you the bake time for every recipe. |
Trade-offs
Change of plan
Go with Ooni Koda 2. The larger rated diameter comes from Koda 2.
Go with Solo Stove Pi Prime. Pi Prime has the lighter published weight.
Decision guide
Pick Koda 2 if a 14-inch pizza is a real requirement or its selected peel-and-cover bundle fills gaps in what you own. Pick Pi Prime for 12-inch propane pizza and a 30-pound body. Both are outdoor gas ovens, and Ooni's recovery claims against Koda 12 give no proof of a recovery advantage over Pi Prime.
The extra diameter on Koda 2 counts when your normal recipe is a larger pizza to share. It may count for little if everyone picks separate toppings on a 12-inch base. The area calculation describes the dough's footprint, whereas the actual meal depends on thickness, toppings and how the pizzas are served.
A 12-inch peel and a carry cover come with the Koda listing. They are useful additions, but they do not prove that the included tool handles every 14-inch launch. Likewise, compare Pi Prime with the tools you already have or plan to add.
Ooni's published improvement is measured against its older Koda 12, not head to head against Pi Prime. For this pair, the credible differences are pizza diameter, listed weight, package and stone design, and no advantage in back-to-back cooking should be invented.
